That he might be the drag on this group was discouraging. In any case Swan was overseeing the filling of backpacks she had found in the emergency supply cabinets: their spacesuit helmets, some emergency air, water bottles, food, air mattresses, a little pot and stove.

Answer: Overlapping and integrating both subjects. On one hand, this book gives a presentation of airplane performance at the college level. It covers both static and accelerated performance topics.
On the other hand, this book also gives a presentation of airplane design, with an emphasis on the philosophy and methodology of design. Some emphasis is also placed on historical material and design case studies in order to illustrate this philosophy and methodology.
This book is not a handbook for airplane design. It is intended to be used in courses in airplane performance as a main text, and in courses in airplane design as an introduction to the philosophy of design, and hence in conjunction with an existing detailed text on airplane design.
To paraphrase a popular television commercial, this book is not intended to make a course in handbook engineering design-rather it is intended to make a course in handbook engineering design better. This author hopes that such intentions are indeed achieved in the present book. The major features of this book are as follows. This book is intentionally written in a conversational style, much like the author's previous texts, in order to enhance the readers' understanding and enjoyment.
The book is divided into three parts. Part I contains introductory material that is important for an understanding of aircraft performance and design. Chapter l deals with the history of aircraft design.
It is important for students and practitioners of aircraft design to understand this history because the design of a new airplane is usually evolutionary; a new airplane is frequently an evolutionary extension of one or more previous designs. Even the most revolutionary of new airplane designs contain some of the genes of almost all previous aircraft.
Hence, Chapter l is an essential part of this book. Other historical notes appear elsewhere in the book. Chapters 2 and 3 are overviews of aerodynamics and propulsion, respectively. These chapters focus on only those aspects of aerodynamics and propulsion that are necessary for an understanding and application of both aircraft performance Part H and aircraft design Part III. However, they serve a secondary function; they provide a self-contained overview of theoretical and applied aspects of aerodynamics and propulsion that help the reader obtain a broader perspective of these subjects.
So Chapters 2 and 3, in addition to being essential to the material in Parts II and III, have intrinsic educational value in and of themselves, no matter what may be the reader's background. Part II deals with static and accelerated aircraft performance. The basic equations of motion are derived in Chapter 4. These equations are then specialized for the study of static performance no acceleration in Chapter 5, and are used in Chapter 6 in their more general form for performance problems involving acceleration.
The material is presented in two parallel tracks: 1 graphical solutions, and 2 closed-form analytical solutions. The value of each approach is emphasized. Parts I and II provide the material for a complete one-semester course on aircraft performance at the junior-senior level. Parts I and II are sprinkled with "design cameos"-boxed discussions of how the material being discussed at that stage is relevant to aircraft design.
These design cameos are a unique feature of the present book. They are part of the overall integrated discussion of performance and design that is a hallmark of this book. Irt addition, many worked examples are included in Parts I and II as a means to support and enhance the reader's understanding of and comfort level with the material. Homework problems are included at the end of most of the chapters, as appropriate to the nature of each chapter.
Part III is all about aircraft design, but with a different style and purpose than existing airplane design texts. Chapter 7 lays out an intellectual, almost philosophical road map for the process of aircraft design. Then the methodology is applied to the design of a propeller-driven airplane in Chapter 8, and jet-propelled airplanes in Chapter 9.
Part III is not a design handbook; rather, it provides an intellectual perspective on design-a perspective that all airplane designers, past and present, exhibit, whether knowingly or subconsciously. Part III is intended for the first part of a senior design course. I wanted to create a book that would work synergistically with existing main-line design texts. As mentioned earlier, this book is not intended to constitute a complete course in aircraft design; rather, its purpose is to make such 'a course a better and more rewarding experience for the student.
There are carefully selected homework problems at the end of most of the chapters-not an overpowering number, but enough to properly reinforce the material in the chapter. There is a Solutions Manual for the use of instructors. Permission is granted to copy and distribute these solutions to students at the discretion of the instructor. In addition, the answers to selected problems are given at the end of the book.
Computer software for aircraft performance and design calculations is intentionally not provided with this book. This may be seen as bucking current trends with engineering textbooks. The reader's experience with software for these subjects will most likely come soon enough in the classroom. However, much of the material in this book is ideally suited to the creation of simple computer programs, and the reader should enjoy the creative experience of writing such programs as he or she wishes.
The Evolution of the Airplane and Its Performance: A Short History Instead of a palette of colors, the aeronautical engineer has his own artist's palette of options. How he mixes these engineering options on his technological palette and applies them to his canvas design determines the performance of his airplane.
When the synthesis is best it yields synergism, a result that is dramatically greater than the sum of its parts. This is hailed as "innovation.
With some likelihood, you will see evidence of an airplane-possibly a small, private aircraft hanging low in the sky, slowly making its way to some nearby destination such as the Cessna shown in Fig. These airplanes-these flying machines-we take for granted today. The airplane is a part of everyday life, whether we simply see one, fly in one, or receive someone or something package, letter, etc.
However, the airplane did not just "happen. It was not until a cold day in December that these laws were finally harnessed by human beings to a degree sufficient to allow a heavier-than-air, powered, human-carrying machine to execute a successful sustained flight through the air.
On December 17 of that year, Orville and Wilbur Wright, with pride and great satisfaction, reaped the fruits of their labors and became the first to fly the first successful flying machine. In Fig. At that moment, the Wright brothers knew they had accomplished something important-a feat aspired to by many before them, but heretofore never achieved. The airplane is the subject of this book-its performance and its design.
The purpose of this book is to pass on to you an appreciation "Of the laws of flight, and the embodiment of these laws in a form that allows the understanding and prediction of how the airplane will actually perform in the air airplane performance and how to approach the creation of the airplane in the first place in order to achieve a desired performance or mission the creative process of airplane design.
By , the Wright brothers had achieved a rudimentary understanding of the principles of airplane performance, and they had certainly demonstrated a high degree of creativity in their inventive process leading to the design of the Wright Flyer. Today, our analyses of airplane performance have advanced much further, and the modem process of airplane design demands even greater creativity. The processes of airplane performance and airplane design are intimately coupled-one does not happen without the other.
Therefore, the purpose of this book is to present the elements of both performance and design in an integrated treatment, and to do so in such fashion as to give you both a technical and a philosophical understanding of the process.
Hopefully, this book will give you a better idea of how the aeronautical engineer mixes "engineering options on his technological palette and applies them to his canvas," as nicely stated by Richard Smith in the quotation at the beginning of this chapter. In this section, the technical evolution of the airplane is divided into four eras: 1 pre-Wright attempts, 2 strut-and-wire biplanes, 3 mature propeller-driven airplanes, and 4 jet-propelled airplanes.
We have room for only short discussions of these eras; for a more detailed presentation, see Ref. If you like aeronautical history, this chapter is for you. However, if you do not particularly want to read about history or do not see the value in doing so, this chapter is especially for you.
Whether you like it or not, good airplane design requires a knowledge of previous designs, that is, a knowledge of history. Even the Wright Flyer in was as much evolutionary as it was revolutionary, because the Wright brothers drew from a prior century of aeronautical work by others. Throughout the twentieth century, most new airplane designs were evolutionary, depending greatly on previous airplanes. Indeed, even the most recent airplane designs, such as the Boeing commercial transport and the F supersonic military fighter, contain the "genes" of years of flying machine design.
If you are interested in learning about airplane design, you need to know about these genes. So no matter what your innate interest in reading history may be, this chapter is an essential part of your education in airplane design.
Please read it and benefit from it, in this spirit. Pre-Wright EraBefore the Wright brothers's first flight, there were no successful airplane designs, hence no successful demonstrations of airplane performance.
However, there were plenty of attempts. Perhaps the best way of gaining an appreciation of these attempts is to go through the following fanciful thought experiment Imagine that you were born on a desolate island somewhere in the middle of the ocean, somehow completely devoid of any contact with the modem world-no television, radio, newspapers, magazines, etc.
And imagine that for some reason you were possessed with the idea of flying through the air. What would you do? Would you immediately conceive of the idea of the modem airplane with a fixed wing, fuselage, and tail, propelled by some separate prime mover such as a reciprocating or jet engine? Certainly not! Most likely you would look at the skies, watch the birds, and then try to emulate the birds.
However, after only a few of these attempts maybe only after one such trial , you would most certainly conclude that there had to be a better way. They were all singularly unsuccessful.
So perhaps you on your desolate island might talce the next evolutionary step; namely,.

Неужели. - Да. После того как я вскрыл алгоритм Попрыгунчика, он написал мне, что мы с ним братья по борьбе за неприкосновенность частной переписки.
- У нас внизу работают лучшие программисты в мире. И мы нашими совместными усилиями даже близко не подошли к математической функции меняющегося открытого текста. А вы хотите сказать, что какой-то панк с персональным компьютером придумал, как это сделать.
На рубашке расплывалось красное пятно, хотя кровотечение вроде бы прекратилось. Рана была небольшой, скорее похожей на глубокую царапину. Он заправил рубашку в брюки и оглянулся.
